Subaru Oil Galley Plug w/ 1/8BSPT Threads

This is a genuine Subaru part that installs in place of the stock WRX & STI oil galley plug, located on the top of the engine block, beneath the top-mount intercooler. This port is plugged from the factory, but runs right into an oil passageway, making it an excellent spot to hook up an oil pressure or oil temp gauge (or both if you purchase a tee fitting from your local hardware store). Sure beats using an oil filter 'sandwich' adapter!

Note:

Subaru plug washer 037018200 is not included with the plug but available separately below.
